Application filed April S, 1905. Serial No. 254,528.

` HAUsEn, of Minneapolis, in the county of Hennepin and State of Minnesota, one of the United States of America, have invented cer-v tain new and useful Improvements in-'Storage-Bins; and I hereby declare that the following is a full, clear, and'exact description of thesame.

p ln my former application for Letters Patent of the United States for improvements in storage-binsiled October l5, 1904, Serial No. 228,649, the Walls are described-as being constructed of concrete and braced by longitudinally-disposed binding-stays having anchor-loops of a pear or kite shape formation. overlapping at the corners ofthe structure fand engaging concrete-anchors forming homogeneous parts of the Walls. This construction'is eminently satisfactory so far as the purposes for which the invention is intended but owing to the formation of the anchor-loops it is necessary to make the binding-stays of a goed quality of metal and to em-- ploy skilled labor t3 shape them., thus adding to the cost of erecting the structure Without imparting any corresponding advantage.

1n the construction described in the abovementioned application centering rods are embedded in the concrete to correctly'pcsition the binding-stays 4as the Walls are erect- I ed, and to place the binding-stays in pesition itis necessary to raise the anchor loops 4to the top of and then lower them down the centering-reds until the binding-stays come into-contact with the erected structure, an'

.Operation which complicates and retards the progress of the Work and adds to its cost.

rl'he present invention relates to the construction of a storage-bin in which the walls are strengthened by truss-rods and tied together at the corners by angular tle-rcds to resist the crushing strains to which they may be subjected when the storage-bin is in use, and the object of the` present invention is to -iorm the truss-rods with anchor-hooks to enage the `concrete anchors extending vertically through them and formingan homogeneous part of the material of which vthe Walls are constructed, the anchor-hooks havinginturned locking members to resist their Withdrawal from the concrete anchorage.

A further feature of the invention is to provide the outer lWalls opposite the cross-walls with strengthening-roda. the ends of such strengthening-rods being of a hook-shape truss-rods and the angular tie and strengthening rods. Fig. 2 is a vertical section taken obli'quely through one o1' the outer corners of the bin` on the lines a a, Figjl. Fig. 31s a `vertical section ytaken transversely through the outer wall at its junction witlrone ofV the cross-walls on the line b b, Fig; 1'. Fig. 4 is a detail view of one of the truss-rcds,` llig. 5 is a detail vieW of one of the angular tie-rods, and Fig 6 is 4a detail View of one ofthe strengthening-reds.

Like letters-of reference refer to likeparts throughout the specifications and drawings.

As the construction of all of the bins' in a four-bin structure is exactly` he same, the description of the construction of one bin Will explain the construction of'the others.

The walls a and ct are built of a cement inixture, and during their erection-the truss-rods b are embedded in them with their anchorhooks c overlapping and correctly centered at the corners of the outer Walls and at the junction of the outer Walls with the cress- Walls. In making the truss-rods `the an'- chor-hooks c are formed by bending the ends ofthe truss-rods preferably into a' semicircular or other suitable hook-shape, as shown in F ig. el of the drawings, :with mtnrned lips d, arranged' tangentially to the curvedor body portion for the purpose of forming locking members to resist the displacement of the anchor-hooks from the concrete*anchorage under the influence of the loa-1l upon the truss-rods.` .In erecting the Wallsfthe trussrods are embeddezl in the 'walls a with their anchor-hooks c located at the corners formed by the walls a and ai. l'Vhenthe truss-rods .7) have been properly positioned in the Walls a, they are preferably covered with a layer -of the concrete 1niXture,'and when covered the truss-rods b are similarly placed in the Walls a with their anchor-hooks c overlappingand correctly centered with the anchor-hooks'of the truss-rods embedded in the walls a; The truss-rods b inthe walls a" are thencovered ICO with a layer ei'gthe cement mixture, and another series oi truss-rods b' are placed in the walls-(1 the 'operation of placing the trussrods in the walls a and a. being'alternately repeated until the-erection of the walls is completed` By having the anchor-hooks c' of thev truss-roos correctly centered and overlappmg a concrete anchor e 1s formefLWhich extends vertically throu'gh the anchor-hooks and .constitutes an 'homogeneous part of the This formation enables thestructure to resist the shearing st-rains at those points byutiizing the full strength of the concrete mixture and truss-rods; To urther'strengthen the structure, angular tie-rods having hook-shaped .-l ends g, are embedded at suitable vertical inter- .vals inthe adjoining Walls at the corners of the structure' and on the outer side of the anchorhooks, sothat the walls a will be securely 'tied to the Walls a. The hook-shaped ends g o'f the angular tie-rods f form anchorages lto prevent the displacement of the tierods4 to enable them to securely fasten the walls together without any possibility of the walls spreading at the corners, under the shearing strains upon the structure. vIn the outer walls a and-a', opposite the junction with them of the cross-walls a, are strengthening.- rods 71 havinghook-shapezl ends fi to -anchor, the strengthening-ro ds in the material to fasten together the outer walls for two azljacent bins j and j and assist them in resisting the shearing strains at the corners formed by the junction with them of the cross-walls.

Extending vertically through the concrete anchors e are centering-pins c of comparatively diminutive diameters to correctly position the anchor-hooks c during the erection of the walls and to reinforce the concrete anchors when the Walls are lerected and the concrete mixture has set. yBy imaking the anchor-hook c of substantial the shape vshown in the drawings it is possible to'pla'ce them in position in the walls ithout having to raise the truss-rods to the top the centering-pins ,and then lowerithemfinto contact with the erected' portion-of the vall, as 1n the case of the construction 'described in my former application. l j y Having thus fully what I claim as new, Lettersv Patent, is'- f1. `A storage-bin comprising walls of concrete material, truss-rods embedded therein,

described my' invention, and desire to secure by crooked anchor-hooks at the ends of the i' truss-rods, embracing a considerable quantity of concrete material, located at the corners of the Walls'and vertically alined with intervening spaces between them, and columns of concrete material extending through the crooked anchor-hooks and engaging therewith and` uniting at the intervening spaces with the concrete material of the Walls.

2L A'storage-bin comprising walls of concrete material, truss-rods embedded therein, crooked anchor-hooks lat the ends of the` truss-rods, embracing a considerable quantity of concrete material, located at lthe corners of the walls and vertically alined with .intervening spaces between them, inturned locking members at the ends of the anchorhooks, fand columns of concrete material extending through the crooked anchor-hooks and engaging therewith and uniting at the` intervening spaces'with the concrete material of the walls.
